Devil's Sea

 The Devil's Sea , also known as the Dragon's Triangle, the Formosa (Taiwan) Triangle ( pinyin: Fúěrmóshā Sānjiǎo) and the "Pacific Bermuda Triangle", is a region of the Pacific around Miyake Island, about 100 km south of Tokyo. The size and area varies with the report (the only reports stem from the 1950s), with various reports placing it 70 miles (110 km) from an unspecified part of Japan's east coast, 300 miles (480 km) from the coast, and even near Iwo Jima, 750 miles (1,210 km) from the coast.(Kusche:259-260)
The area is said to be a danger zone on Japanese maps, according to Charles Berlitz's books The Bermuda Triangle (1974) and The Dragon's Triangle (1989). He states that in the peacetime years between 1952-54 Japan lost 5 military vessels with crews lost totalling over 700 people and that Japanese government sent a research vessel boarded by over 100 scientists to study the Devil's Sea, and that this ship too vanished; and finally that the area was officially declared a danger zone.
                 In the early 1950s they decided to dispatch a research vessel to study the area. Despite enjoying good visibility and calm seas, the Kiao Maru No.5 disappeared without trace on 24th September 1952. The lives of all twenty-two crew and nine scientists were lost. The vessel has never been found. It has only been in relatively recent years that these incidents of strange disappearances have been reported in the West. To the Japanese, they are regular occurrences which stretch back for centuries and continue to this day.
